Last I heard the day for him to be back in the lineup was backed up to Friday (today). Still waiting to hear if that is still going to be the case.

From KFFL"Jul 26 Joe Frisaro, of Marlins.MLB.com, reports Florida Marlins SS Hanley Ramirez (shoulder) worked out with the team Wednesday, July 25. Ramirez stretched with the team during warm-ups and tested his injured shoulder by fielding grounders. Ramirez is expected to further test his shoulder by taking soft-toss swings in batting practice Thursday, July 26, and could be ready to return as early as Friday, July 27. "

Speculation is he will be in sometime this weekend, but it will probably take him a few weeks to get back to the production we are all used to... but since you never know, your probably going to want to put him in the lineup just in case.
